PORTABLE ADJUSTABLE H EAD -REST.

CLZFCIFICATKQN forming part of Letters Patent No. Se l-{726, dated June29, 1886 (.\'0 model.)

To aZZ whom it may concern:

1 Be it known that 1, Gnoncn E. DOLTON, of the city of St. Louis, Stateof Missouri, have made a certain new, useful, and valuableIniprovementin Portable Adjustable Head-Rests, of which the following isa full, clear, and exact description, reference being had to the annexeddrawings, in which Figure 1v is a perspective view of front of head-restraised; Fig. 2, rear view of same, Fig. 3, side elevation of head-rest,showing headrest as attached to the back of a car-seat ready for use;Fig. 4, side elevation of head rest, showing the head-rest turned backin another position from that shown in Fig. 3; and Fig. t shows indotted lines the headrest dropped down in another position. Fig. 5 is aview showing the arms I) and E pivoted by a pin instead of a set-screw.

The object of my invention is to provide a portable device, which can beattached to the back of a chairor car-seat and adjusted in any positionof rest for the head which the desires of comfort may dictate; and itconsists, essentially, of a device for gripping the back of a chair orcar-seat, a cushion or pad for the head i to rest upon,adjustably-connected arms piv oted to each other, so as to form threepivotal joints, by means of which the cushion and gripping device areconnected together, and by means of which the cushion is adjusted to anydesirable position of comfort and rest for the head. I have discoveredthat two pivotal joints or connections for adjustable arms connectingsaid cushion and gripping device together will not suffice to allow theadjustment of the cushion to varied positions of comfort and rest forthe head, but with the addition of a third joint, providing a means ofadjustment, the desired amount of play and opportunities for placing thecushion at varied and desired positions are obtained.

The construction of my invention is as follows: The device for grippingthe back of the chair or car-seat is preferably in the shape of agripping-spring made by bending a piece of suitable metal into a bow orU shape, and in practice I preferably make one of the ends of thisU-shaped gripping device longer than the other, and provide this longerend with a thnmbscrcw and block, asshown in the drawings, but this isonly my preferable construe tion, for I have found that a simple bow orU-shaped gripping device will hold the headrest mechanism in place onthe back of a carseat by virtue. of the elasticity and grip of such U orbowshaped piece of metal when forced over the back of acar seat. Thisgripping device I have lettered Ain the drawings. Preferably I providethe grip A with a socket, a, into which a pin, B, with a rounded shank,is dropped. This pin Bis controlled in its position in socket a by meansof a thumbscrew, 2). The head of the pin 13 is preferably broad andflat, and is provided with a hole, the object of which is to provide ameans of connecting one end of a pivoted adjustable arm, 0, with the pinB and the gripping device A; and I preferably have the surface of thehead of the pin B cogged, so that such surface maycome into play with acorrespond ing surface in the end of arm Qenablingthesc two pieces to beheld firmly in a desirable position, as hereinafter stated.

Thefirst of the pivoted arms I designate as O. This arm O,Iprefcrablyform oftwo pieces, as shown particularly by Fig. 2 of thedrawings. The object of forming this arm, as there shown, in two piecesis to afford the op-- portunity for making a good pivotal connectionwith pin B, the lower ends of the pieces of arm G being preferably flat,and preferably having a coggcd face corresponding to the cogged surfaceat the head of pin I3, and provided with a hole corresponding to thehole in the head of pin B, by means of which the shank of the sametlinnibscrew passes through the lower ends of the pieces that form arm0, and through the head of pin 13, thus forming a connection or jointbetween the head of the pin B and the lower part of arm G, which is aconnection which may be regulated so as to be either a loose or pivotalconncction between pin B and arm 0, or a rigid connection between thesetwo parts. The upper ends of the pieces forming arm 0 are pref erablybroad and flat, and preferably provided with a cogged surface, for thepurposes stated, and are also provided with holes, and between theseupper ends of arms O a like end of arm I), which is also provided with ahole, and preferably cogged for the purposes stated, is placed, and anadjustable and plvotal connection orjoint, Y, is there formed betweenthe arms and D by passing the shank of a'thumb screw through theseopenjustable connection or joint, Z, is formed between arms D and Eloyinserting the shank of a thumb-screw through the holes in the ends ofpieces forming arm E, and through said end of arm D. I say thisconnection between arms D and E may be made by means of the shank of atl'inmb'screw, but a thumbscrew to form this joint is hardly necessary,for it is advisable, generally speaking, to have this connection betweenthe arms D and E a loose pivotal connection, it having been found inpractice that it is almost never desirable to have that connectionrigid.

It will readily be seen that my third pivotal ad nstable connection or jointZ may be formed by dispensing with the rigid pieces forming arm E,and by pivoting the end of arm D directly to frame of cushion F; but thecmstruc- .tion shown is my preferable one.

My pivoted adjustable arms 0, D, and E, as also the rest of my device,excepting the cushlon-pad, are preferably made of metal.

My cushion F consists, essentially, of a back piece or frame-work towhich the end of arm E not connected with arm D is rigidly attached, orinto which arm D may be pivoted, as before stated. The face of cushion Fis covered with some soft material for the head to'rest upon.

As a preferable addition to my device, by means of a thumb-screw'Iattach a pivoted arm, G, to my cushion F. This arm G is bent at its end9 to form a side piece for cushion F, and the end 9 of arm G is padded.

The operation of my invention is as follows: The thumb-screws connectingarms 0, D, and E, and the cushion F and the grip A together beingloosened, as is readily seen, my headrest can be dropped forward anddown into the back of the seat and there adjusted in any positiondesirable. It can be dropped back into the positions shown in Fig. 4 ofthe drawings, to form arest in any suitable position for a person on aback seat, and with its peculiar facilities for adjustment my device canbe used to rest the head of a child or of a tall grown person. When anydesirable position has been reached, my device can be arrested in thatposition by tightening thumb-screws,- but, as previously stated, thethumb-screws connecting arm 0 to grip being tightened and thethumb-screws connecting arms 0 and D together being tightened, it isdesirable not to tighten the thumbscrew connecting arm D and E together;but it is desirable to let this connection or joint between arms D andE, or between arm D and frame of cushion F, remain a loose connection.The attachment formed by the pivoted arm G and its padded end is ofadvantage in preventing the head from slipping from the cushion.

I am aware that a single arm pivoted to a head-rest and to an adjustablerod or fastening device,which is secured to the back of a chair is notnew, and I do not desire to claim the same.

I amalso aware that portablehead-rests are described in Letters PatentNo. 242,380, dated May 31, 1881, and I not desire to claim the same.

I claim- 1. In a portable adjustable head-rest, the combination of thearms 0 D, pivotally connected with each other, a head-rest, F, having adetachable arm, G, said rest being pivoted to the arm D, and a gripper,A, to which the arm 0 is adjustably pivoted, substantially as and forthe purposes specified.

2. In a portable adjustable head-rest, the combination of the double bar0, single bar D, and adjustable pin 13, pivotally connected bythumb-screws, and a head-rest, F, to which the bar D is pivotallyconnected, substantially as and for the purposes specified.

In testimony whereof I have affixed my signature, in presence of twowitnesses, this 13th day of August, 1885.

GEORGE E. Dom-on.
